Weierstrass多项式系统,最初定义为收敛幂级数环中的理想,连同它的次数序列允许我们直接分析齐次理想。利用它,我们研究了局部上同调模,合偶,然后分次Buchsbaum环。我们的结果给出了一个公式,在一定程度上澄清了从Weierstrass多项式系统开始的自由分解中出现的矩阵之间的联系,在一般情况下,分次Buchsbaum环的粗略分类和余维2的分次Buchsbaum整环的完整分类。
The system of Weierstrass polynomiajs, defined originally for ideals in convergent power series rings, together with its sequence of degrees allows us to analyze a homogeneous ideal directly. Making use of it, we study local cohomology modules, syzygies, and then graded Buchsbaum rings. Our results give a formula which to some extent clarifies the connection among the matrices appearing in the free resolution starting from a system of Weierstrass polynomials, a rough classification of graded Buchsbaum rings in the general case and a complete classification of graded Buchsbaum integral domains of codimension two.
